Improvement in water-elevators



UNITED STATES PATENT Ori-ICEC PHILANDER ANDERSON, OF N ORWIOH, NEW YORK,ASSIGNOR TO HIMSELF AND P. K. BRONSON, OF SAME PLACE.

IMPROVEMENT IN WATER-ELEVATORS.

Specific-ation forming part of Letters Patent No. 35,711, dated May 26,i363.

To all whom it may concern.:

Be it known that l, PHILANDER ANDER- SON, of Norwich, in the county ofOhenango and State of New York, have invented a new and usefulImprovement in Frictional Windlasses for WaterElevators; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, making a partof this specification, in which- Figure l is a vertical section of theinvention, taken longitudinally through the ropebarrel B. Fig. 2 is aninside view of the head of the crank C, showing the relative arrangementof the ratchet-ring R, spring s, and pins c and c, as in action with theannular flange or friction-ring a of the head h. Fig. 3 is a detachedview of the ratchet-ring R. Fig. 4 is a face View of the head h, showingits friction-ring a.

This invention relates to that class of waterelevators which areoperated by frictional windlasses, and its nature will be clearlyunderstood by reference to the drawings and specification.

Similar letters of reference indicate corresponding parts in all thefigures.

The heads H and H may be cast, and are fixed to the rope-barrel B byscrews or otherwise. The journals J and J may be cast to the heads. Thebearings B B are bolted to the top ofthe curb. The head his keyed orotherwise rigidly xed to the elongated journal J, and it is providedwith an annular projecting ange or ring, a, tolwhich is loosely fittedthe ratchet It. This ratchet has an inner flange, in which is formedseveral cam-reces'fes, m, in, any one of which the pin c of thecrank-head may be placed, as seen in Fig. 2. One end of the spring stakes in one of the notches n in the ratchet-rin g R, and the other endrests against the pin e. This spring encircles the journal J with one ortwo turns, the journal answering as a steady-pin to keep it in position.The crank G also turns loosely upon the shaft or journal J, to which itis secured by the burr or wash er w and pin a, or other equivalentdevice. The pins c and e may be cast on the crank-head.

Operation: The spring s, as seen in Fig. 2,

raising the bucket, the opposite side of the ratchet is thereby firmlyclamped against the friction-ring a of the tight head h, forcing it andthe barrel B to rotate with the crank. To allow the bucket to descend,itis only necessary to reverse the crank C, moving it in the directionindicated by the full-line arrow, which brings the pin c back, as shownby the dotted line c', into the deeper portion of the'recess m, thusreleasing the ratchet, (it being prevent-ed from following the crank inthis direction by the pawl P, shown by dotted lines, which is pivoted tothe frame or curve,) when it assumes its concentric position, indicatedby the dotted circle f entirely relievingits pressure against thefriction-ringo., and thereby permitting the bucket to descend, therapidity of its descent being entirely under the control of theoperator, it being governed by a greater or less pressure of the ring cagainst the curved back of the recess m, making more or less frictionbetween the ratchet It and ring a'.

The advantage in having several recesses m and notches n in the ange ofthe ring R is, that when the side bearing against the friction-ring ashall have become worn, it may be turned so as to place the pin c andthe end of the spring s in the next recess m and notch n', therebyrenderingit much more lasting. This change is effected by simplyremoving the crank and changing the end of the spring to the next notch,then adjusting the crank with pin c behind the opposite end of thespring s, as shown inFig. 2, and turning the crank backward until thepin c drops in one of the recesses m. The action of the spring may bestrengthened by spreading its ends, so as to require more of a turn ofthe crank before the recess m shall receive the pin c, and vice versa.

The pin c may be provided with a frictionroller, if desired, to renderit more sensitive in its action and to decrease the wear upon it.

I claim- The pin c, attached to the head of the crank C, or itsequivalent, and the cam-recess m, of the ratchet-rin g R, in combinationwith the friction-ange a, spring s,pin e, and pawl P, substantially asand for the purposes specified.
